More Than Just a Garden Hose
Over time, concrete accumulates layers of dirt, moss, algae, and oil that a standard garden hose simply cannot remove. Not only does this look unsightly, but organic growth like moss can trap moisture and accelerate freeze-thaw damage.
Gaetano Cement Contractors uses industrial-grade Surface Cleaners (the large round disc units) rather than just a pressure wand. This ensures a consistent, streak-free clean without the "zebra stripes" often left by DIY pressure washing.
Why Professional Cleaning Matters
Concrete is durable, but it can be damaged by improper cleaning. Using too much pressure with the wrong tip can etch the surface ("cream") off the concrete, exposing the aggregate permanently. We adjust our pressure and flow rate to clean effectively without damaging the finish.
Our Cleaning Process
We use a systematic approach to lift deep-set stains:
| Step | Description |
|---|---|
| 1. Pre-Treatment | Application of a biodegradable degreaser or mild algaecide to loosen organic matter and oil. |
| 2. Surface Cleaning | We use a rotary surface cleaner that hovers over the concrete, delivering uniform pressure to lift dirt. |
| 3. Hot Water Rinse | For stubborn oil or gum, we use hot water units (up to 200°F) to melt away residue. |
| 4. Post-Treatment | A final rinse to ensure all detergents are removed, leaving your concrete bright and neutral. |
Frequently Asked Questions
Will pressure washing remove oil stains?
We can significantly improve the appearance of oil stains using hot water and degreasers. However, if the oil has penetrated deep into the concrete for years, a faint "shadow" may remain.
Will the chemicals kill my grass?
We take great care to pre-wet surrounding vegetation, which dilutes any runoff. We use biodegradable cleaners that are safe for lawns and landscapes when used correctly.
Should I seal the concrete after cleaning?
Absolutely. Cleaning opens up the pores of the concrete. Sealing it immediately after it dries locks out future dirt and salt. Ask about our Clean & Seal Package.
